Specification of Letters Patent.

Patented May 4, 1909.

Application filed 11113 20, 1908. Serial N0. 444,3 4.

T all whom it may concern:

Be it known that I, BENJAMIN C. Fox, citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Refuse-Burners, of whichthe following is a specification.

My invention relates to improvements in receptacles designed to holdpaper and other waste material, to be burned without removal from the"container. j

The chief objects of the improvements which form the subject matter ofthis application are :to provide a repository for loose and inflammablematerial so constructed as to permit access of airto every part of thecontained mass, so that free combustion may take place without resortingto artificial draft; to so design and construct the receptacle that theentire contents may be con sumed Without danger of communicating thefire to surrounding objects; and to supply a portable combined furnaceand receptacle that will be durable, economical to manufacture, andcapable of causing complete incineration. of the contents.

Other objects of my invention, statcd more in detail, are:to provide arefuse burner constructed largely of opcn-worlc material, such asexpanded metal, thus producing a receptacle of light weight propor--tional to its capacity; to furnish a rigid frainc for reinforcing and soporting the perforated material, and to supp y means for protecting theraw edges of the expanded metal where cut.

A further advantage is observable in the removabili'ty of the grate andextension, the latter adapted to admit air into the center of the masswhen burning, thus promoting complete combustion.

Another feature of importance is the shape in which the parts are made,the outer we ls being in the form of a truncated cone, and

the inner member conical, thus pern'iitting the parts to be nested so asto economize space for transportation.

I accoln l" h the desired results by means of the device illustrated inthe accon'ipanying drawing, forming a part of this application, and inwhich Figure 1 is a side elevation of the preferred form of my improvedrefuse burner; Fig. 2 is a vertical section on line 2 2 of Fig. 1 l ig.3 is avertical section, with seine portions .broken away, showing amodification in the l t l i i construction of the grate supports, andFig. 4 is a top plan view of the grate shown in Fig. 3 and supportstherefor, removed from the receptacle.

Referring to the details of the drawing, the numeral 5 indicates abasket-like receptacle, having the general shape of an invertedtruncated cone. I prefer to use expanded metal for the walls of thisreceptacle, although woven wire fabric. may be substituted if preferred.The upper and lower ends of the receptz'rcle arc reinforced andprotected by metal bands 6, 7, of U-shape'or channel form, which areriveted thereto. The-sides of the receptacle are stiffened by' verticalmetal strips 8 placed upon the outside at spaced intervals, and rivetedat their ends to bands 6 and 7 by rivets 10, which pass through thestrips both walls of the bands and the expanded metal. The strips 8 arefurther secured to the expanded metal sides by additional rivets l]. Thestructure thus described is formed with both ends open, and to supportthe contents a grate 12 in the form ofain annular ring or plate having acentral circular opcning 1;}, and j'irr'ividod with a plurality ofsmaller apertures 13 to permit. the air to pass freely during theprocess of combustion is arranged within the rcccptsclc. This grate issupported at a slight distance above the lower margin of the receptacleby a framework consisting of two hangcrs lat, which are dirccted radiall\'.bcncath the said grate, and fastened thcrcto by rivets 'lhcllllrltilOPUl'lrlOll of eachhanger is bcnt at the inner margin of thecentral opening .13 of the grate and extended upward in the mannershown, forming an invcrtcd V, lti, the apex of which is indicated at 17,where the two hangers cross each other. The outer portions 17 of thehangers are bent sharply upward at the periphery of the grate 12, andlie parallel with and against the inner surface of the receptacle wall,where the extremities are recurved to form hooks 18 (as shown in Figs. 1and 2) which pass through the walls of the lt-BCQP- taclc and arereceived in suitable openings 19 formed in the supporting straps 8, thusaffording a firm support for the grate, and permitting its ready removalby disengaging the hooks, which may be done by raising the grate andhangers, the -o cn.ings 19 being of suflieient height to permit this tobe easily done, and then springing the hangers inwardly until thehooks'are free. The mid- (He portions of the hangers form a sup aort fora cone-shaped member 20, whic is placed over the said support andriveted thereto as shown at 21. This cone is preferably constructed ofthe same material as the wall of the receptacle, forms acovering for thegrate opening 13, and permits the air to penetrate freely to the centerof the burnomitted, the frame portions 17 being permanently secured tothe receptacle walls by rivets 24. While in this case the grate is notdetachable the cone can be lifted therefrom. It is apparent that thiscone is subjected to the maximum degree of heat generated in the burningmass, and it is therefore likely I to become deteriorated before theouter structures or the heavier supports and in such case can beeconomically and conveniently replaced by a new cone.

The reinforcements 8, comprising the vertical outside straps, and, thehangers with their V-shaped extensions 16, afford a valuable and durableframework, very essential in a structure composed of the material havingthe light weight which it is desirable to employ for the main walls. Notonly does this frame defend the appliance against rough usage but alsoprevents the Warping to which the light fabric may be liable articularlywhen unusually heavy refuse is burned, the central apex of the cone 20being especially prone to become deflected without the 3 support givenby the V-shaped portions of ie support and maintain same in normalshape.

2. In a refuse burner, the combination with a perforated rec'eptacle,-of channeled bands engaging the ends of the receptacle, verticalreinforcing members secured'at each end to said bands, an annular'gratcprovided with a central opening, hangers supporting said grate andremovably attached to the re- 'ceptacle abovcthe grate, said hangersprojectingupwardly through the central opening in the grate, and aperforated air supplier supported by the projecting portions of thehangers and arranged above the central opening in the grate.

3. In a refuse burner, the combination with. a perforated receptacle,bands engaging the ends of the rece tacle vertical reinforcing stripssecured to t e receptacle and bands, an annular grate having a centralopening, a conical air supplier arranged above said opening, hangersextending across the interior of the receptacle and supporting thegrate, the ends of said hangers being bent to project upwardly above thegrate and terminating in hooks removably engaging openings in thereinforcing straps.

In testimony whereof I afiix my signature in the presence of twowitnesses.
